The duo's self-titled album sold 116,000 copies to give the pair its first No. 1 and best sales week.

The Civil Wars take over Billboard's summit after selling 116,000 copies of their self-titled sophomore album, according to Nielsen SoundScan. It's the duo's best sales week and first No. 1.

It's also somewhat of a bittersweet victory, given that Joy Williams and John Paul White have been on hiatus since November over "internal discord and irreconcilable differences of ambition."

The highly acclaimed new album was recorded in Nashville between August and January "amidst a grueling touring schedule, exhausting workload and a growing disconnect from their families," according to a release today. Read personal statements from Williams and White at thecivilwars.com.

Barton Hollow, the pair's Grammy-winning debut, peaked at No. 10.

The Now 47 hits compilation enters at No. 2 with 82,000, while Robin Thicke's Blurred Lines, last week's chart-topper, slides to third with 65,000. Jay Z is No. 4, and Asking Alexandria's From Death to Destiny makes its debut at No. 5 with 41,000. In a preliminary SoundScan report, Asking Alexandria placed sixth, but revised figures pushed the album up a notch, giving the band and its label, Sumerian Records, their highest openers ever.

After the Teen Beach soundtrack, Imagine Dragons and Five Finger Death Punch, gospel singer Tye Tribbett's Greater Than makes its debut at No. 9 with 30,000. Florida Georgia Line closes the top 10.

On the song side of the charts, Robin Thicke continues to dominate summer. The top five downloads:
